Great find I hadn't seen it. Nothing too surprising in there I wasn't aware of. Even absent the soon to pass legislation, these new rules alone will be sufficient to make carrying contraband so painful for Chinese logistics companies that it's hard to see how anything illegal (that's not worth a fortune per kg and therefore worth taking the risk to smuggle hidden in something else, which AAS are not), that it hard to see how this isn't the end of the UGL market as it's been for the last few years.
Although, admirably, no one seems too freaked out over their packs being opened and sent on rather than seized, my guess is it's intelligence gathering for the new enforcement phase that will kick in 3 months from now.
I really hope this doesn't stop peptides, but because of the "complying with consumer safety" requirement it might.
The bottom line is this. Unless you want to roll the dice on sky high prices and sketchy availability with whatever new market replaces the current one, probobly stuff smuggled in the old fashioned hard/high risk way to domestic vendors, you really need to "Stock up" right now.
The 90 day clock is ticking, and as a practical matter it's probably not that long.
As this document notes, many companies are already complying with the stricter requirements voluntarily to prove they have nothing to hide, so containers with just their stuff get let in without being searched searched from top to bottom.
It's happening, the primary way Chinese UGLs get stuff to the US is ending, there is no "return to normal" after this.
